Clean water leakage management

TMA (Trunk Main Areas), DMA (District Meter Areas), and PMA (Pressure Managed Areas) are essential to managing a resilient and reliable network. Veriflo supports the full lifecycle of these tiles, from initial design through validation and optimisation.

We combine desktop analysis with on-site validation to asset status and operability boundary integrity, as well as pressure data.

We also support network reconfiguration and targeted performance improvements.

Key activities:

• Creation: set up new areas, flush and test assets, commission meters
• Validation: review existing structures, verify meter accuracy, confirm boundary performance
• Optimisation: identify improvements for leakage, pressure and operational efficiency

Why it matters:

• Enhances leakage visibility and control
• Improves network resilience and demand forecasting
• Supports regulatory reporting and ODI outcomes

Accurate data underpins network decision-making. Veriflo provides pressure, flow, and acoustic logging to help clients understand network performance, track anomalies, and detect emerging issues early.

Our team installs and manages loggers, analysing logger data to support everything from leakage detection to pressure management planning. We work with client systems and provide clear data outputs.

Key activities:

• Pressure logging: desktop packs, install, live data download, transient analysis
• Flow logging: verification of meter data accuracy and database corrections
• Acoustic logging: installation and maintenance with high signal coverage

Why it matters:

• Identifies pressure drops, bursts, and leaks early
• Supports optimisation of PRVs and DMA validation
• Improves data accuracy and operational visibility

Reducing leakage is a regulatory and operational priority. Veriflo supports leakage programmes using a blend of acoustic detection, step testing, and zone-level analysis to localise and quantify losses efficiently.

We validate DMA structures, carry out isolation-based step testing, and identify flow anomalies, helping water companies achieve leakage targets and maintain customer service levels.

Key activities:

• Acoustic leak detection using specialist equipment
• Step testing with live flow analysis by zone
• LCA setup and optimisation for ongoing monitoring

Why it matters:

• Accelerates leak detection and reduces runtime
• Enables targeted investigations and cost-effective repair
• Supports ODI commitments and network efficiency

Secondary meters provide essential visibility in complex or shared water supply scenarios. Veriflo installs and validates secondary metering to improve data accuracy and support billing, leakage, and asset planning.

We carry out on-site surveys, verify meter performance, and install new metering where required—including integration with logging and telemetry where needed.

Key activities:

• Validation of existing meter readings and configurations
• New secondary meter installations
• Integration with flow logging and data systems

Why it matters:

• Improves sub-zone level accuracy
• Helps identify consumption anomalies
• Supports water balance and leakage investigations

Our expert team provides desktop analysis and field investigations to identify and implement pressure management solutions. By optimising PMAs, we help stabilise pressure profiles, minimise leaks, and reduce burst incidents.

Our services include:

• Deploying pressure loggers to assess network performance.
• Estimating leakage savings by analysing pressure trends.
• Implementing PRV (Pressure Reducing Valve) solutions using leading brands such as Technolog and HWM.

Controlling pressure is a proven method to reduce burst frequency, leakage, and energy costs. Veriflo supports pressure management schemes through assessment, optimisation, and the design and commissioning of PRV-based control systems.

We combine desktop studies with on-site monitoring to identify reduction opportunities and stabilise pressure across PMAs, improving network resilience.

Key activities:

• Pressure logging and analysis
• PRV optimisation and controller commissioning
• PMA planning and reconfiguration

Why it matters:

• Reduces leakage and burst incidents
• Extends asset life and improves customer service
• Enhances network control and performance insight
